Hearing For The First Time

Being apart of the developmental group, I decided to focus on
children that were born deaf and with Cochlear implants
were able to hear for the first time. Imagine being born into a completely
silent world. The fact is that about 2 to 3 out of every 1,000 children in the
United States are born deaf or hard-of-hearing. Hearing loss can take place in
any part of the ear.

Birth
defects in of the outer or middle ear can be because of buildup
of fluid behind the eardrum, birth defects that cause changes in the structure of the ear
canal or middle ear, injury to or rupture of the
eardrum, or objects becoming stuck in the ear canal.

Birth defects of the inner ear
can damage the tiny nerve endings can be due to exposure to certain toxic
chemicals or medicines while in the womb or after birth, genetic disorders, infections
passed from the mother in the womb, problems with the structure of the inner
ear, or tumors.

As far as treating deafness in
infants there are a couple options you can choose from. The first being surgery
to correct structural problems of the ear. The second being Cochlear implant
which is surgically implanted and bypasses the damaged inner part of the ear to
stimulate the hearing nerve directly. The implant converts sound waves to
electrical impulses in a way that mimics your natural hearing.

Perception

The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
